Consultant hyped up Nihongo Center… but I don’t wanna get scammed 😭 Any good Osaka language schools?

My consultant suggested Nihongo Center, but I’m not sure how good it actually is.
Has anyone here studied there or heard anything about it?

Also, I don’t wanna rely on just one option, so if you guys know any good language schools in Osaka, please drop some names! That’s the city I’m hoping to live in.

And btw, is Osaka still safe these days? I’ve been seeing stuff online about protests and some tension toward foreigners, which kinda worries me.
I always thought Osaka people were super chill and friendly, and that’s honestly one of the reasons I wanted to go there.
